ci: render step results and version in workflow reports (#7141)

* ci(upgrade): render an upgrade matrix in the report; fix from default

The upgrade report only ever showed the requested deb URLs and a case
table. The nightly chain runs died installing the OLD package (default
from_version 1.0.0-rc.4-preview.1 has no .deb asset on its release, and
release 1.0.0-rc.4 ships none either), leaving an empty Total: 0 report
with no indication of what was upgraded.

- Default from_version is now 1.0.0-rc.3 (ships rustfs_1.0.0.rc.3_amd64.deb).
  Matches the auto-testing default from PR #32.
- The report generator also parses the [UPG-TOPO] lines the suite now
  emits and renders an 'Upgrade Matrix' section: per topology and KMS
  backend, the versions actually in place before/after (captured via
  'rustfs --version' on the node) and the aggregated result. When the
  suite dies before any topology completes, the matrix says so instead
  of silently showing nothing.

* fix(ci): use English headers in the upgrade matrix table

* ci(heal,pool): render step results and version in the reports

The heal and pool-expansion reports were only a raw log tail: no
structured indication of which steps passed, no overall verdict, and no
version information for the cluster under test.

The suites now emit machine-readable lines (auto-testing PR):
  [HEAL-STEP] <n> <desc> PASS|FAIL     [POOL-STEP] <n> <desc> PASS|FAIL
  [HEAL-VERSION] <ver> (node <n>)      [POOL-VERSION] <ver> (node <n>)
  [HEAL-RESULT] PASS|FAIL <detail>     [POOL-RESULT] PASS|FAIL <detail>

Both report generators parse them and emit a '## Step Results' section
before the log tail: the version captured in place via 'rustfs --version'
on a node, the overall verdict, and a per-step table. When a run dies
before any step reports (old script or early crash), the table shows a
NOT RUN placeholder row instead of silently showing nothing.
